GUSTAV H. W. SIMMON, OF ST. LOUIS, MISSOURI, ASSIGNOR TO J. F. VOGT BRO.,.OF SAME PLACE.

SWlNGlNG COUNTER-SHAFT FRAME AND BELT-TIGHTENER SPECIFICATION forming part of Letters Patent No. 349,462,6ated September 21, 1886. Application filed January 19, 1886. Serial No. 189,067. (No model.)

To all whom it may concern.-

Be it known that I, GUSTAV H.W. SIMMoN, of St. Louis, in the county of St; Louis and State of Missouri, have invented a new and Improved Swinging Counter-Shaft Frame and Belt-Tightener, of which the following is a full, clear, and exact description;

The object of my invention is to provide an apparatus whereby the use of loose pulleys and belt-shifters is avoided, and whereby the tension on the belts may be regulated in accordance with the requirements of the work to be performed by the machine in connection with which our apparatus is arranged.

My invention will first be described, and then specifically pointed out in the claim.

Reference is to be had to the accompanying drawing, forming part of this specification, in which the figure represents a side view of the frame and its-connections.

A represents the counter-shaft frame, journaled at B. The shaft D carries two fast pulleys, E F, motion being imparted to said shaft by a belt, G, which extends from the pulley E .to the pulley H, carried by the main-line shaft I in the ordinary manner. The above devices are of the well-known construction and arrangement. In order that the frame may be moved upon its journals or pivots, I connect the rod L to the outer or free end of the frame. Below the frame is pivoted a lever, N, upon the long arm of which there isloosely mounted a weight, 0, said weight being free to slide between the pivotal support 1? of the 5 lever N and a stop, Q, that is held to the The lever-arm by means of a setscrew, 0.

short arm n of the lever N projects upward from the long arm of said lever at an angle of about one hundred and thirty-five degrees, and is connected to thelower end of the rod L, which, as stated above, is pivotally connected to the extending end of the frame A. With this construction it will be seen that when the long arm of the lever is moved to a position so that it will be in about a horizontal line, the frame A will be elevated and the belts subjected to sufficient strain, to impart the necessary motion to the pulley J, and this strain or tension upon the belts may be regulated by moving the weight 0 away from or toward the pivotal support P of the lever N. WVhen the belt K is to be thrown off from the pulley J, the lever N is raised to about a vertical position, which movement of the lover will operate to carry the other parts of the apparatus to the position shown in dotted lines.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

.The combinatiomwith the main-line pulley and its belt, of a pivotal'ly-mounted frame, A, carrying shaft D and pulleys E F, a belt, K, driving-pulley J, horizontal lever N, pivoted at I, and having upward-inclined short arm n and a sliding weight, 0, on its long arm, and the vertical rod L, connecting the free end of the frame A with the end of the inclined arm n, substantially as set forth.
